Fatigue

Fatigue
Fatigue is a state of awareness describing a range of afflictions, usually associated with physical and/or mental weakness, though varying from a general state of lethargy to a specific work-induced burning sensation within one's muscles. Fatigue is a non-specific symptom, which means that it has many possible causes. Fatigue is considered a symptom, as opposed to a medical sign, because it is reported by the patient instead of being observed by others.

  • Sleep actually may improve with age, opposite of what was previously thought
    It is generally thought that older people tend to suffer poorer sleep than their younger counterparts, but researchers in a recent study reveal the opposite, that sleep quality appears to improve over a lifetime.
  • Citing poor quality control in a number of specific experiments, the journal Science has retracted an October 2009 study investigating chronic fatigue syndrome (CFS) identifying an infectious retrovirus called xenotropic murine leukemia (XMRV) in a majority of the patients affected by CFS.

  • A group of 26 of the nation's leaders in medicine, health care, patient safety, and research today called for sweeping changes in the design, supervision and financing of U.S. hospital residency care programs to protect patients from serious, preventable medical errors, and end dangerously long work hours for physicians in training.
  • Chronic fatigue syndrome (CFS) is characterized by unexplained and debilitating tiredness and is associated with headaches, disrupted sleep, muscle pain and difficulty in concentrating. New research published by BioMed Central's open access journal BMC Medicine shows that ethnicity, depression, lack of exercise or social support, and social difficulties are major risk factors for CFS.
  • Poor sleep quality is associated with greater disability in rheumatoid arthritis patients
    A study in the Feb. 15 issue of the Journal of Clinical Sleep Medicine found that poor sleep quality correlated with higher levels of depressive symptoms, greater pain severity, increased fatigue, and greater functional disability in patients with Rheumatoid Arthritis (RA). The study suggests that addressing sleep problems via pharmacological or behavioral interventions may have a critical impact on the health and lives of patients with RA.
  • What can scientists learn from watching a group of people sitting around, chatting, playing movies, reading, and happily making new friends?
